Hi Nicole,

Thanks for your clarification that our customer is using the 1G/10G in 1G/10GbE and 10Gbase-KR PHY IP core.

Please see my comments as following:

1. check the LTD and LTR. The CSR address 0X464H is all FFs.

[CP] As I understand it from the user guide, the 0x464 for 1G/10G PHY is referring to pma_rx_set_locktoda

ta. Can you help to check on 0x466 (pma_rx_is_lockedtodata) and 0x467 (pma_rx_is_lockedtoref) to see if the CDR is in LTD or LTR mode.

2. With reference to the 0x400 register, as I understand it, the 1G/10G PHY seems does not support this register. Just wonder if our customer is referring to other register?

By the way, I notice that you have open another Forum case 4591444 in which the TX seems to have no output. Not sure if the TX no output issue is causing the RX issue that we are seeing in this case? Or if there are separate issues.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin

    Hi Chee, Thanks. We will try. These two issues are all in the same project, but not related. This issue is caused by fiber re plug. That issue is caused by recompilation. Thanks for all your supports! Regards， Nicole

      Thanks lot. By the way, would you mind to share the .qsys file of your 1G/10G IP? I seems could not locate in the case. Thank you. Best regards, Chee Pin
